Definitions

  • the present disclosure relates to a cutting tool. More specifically, the present disclosure relates to the cutting tool which allows easy and ergonomic handling for common users.
  • Cutting tools such as secateurs, loppers, rakes, pliers are used for performing cutting action using one or more blades. Put simply, such tools provide increased mechanical assistance and ease of operation to a common user to conveniently perform operations such as with branches of varying dimensions. But application of conventional cutting tools may involve hardships due to the need for a user to frequently apply cutting force. Further, the cutting tools provide benefits such as trapping bypass cutting or simply “bypass” allows pruning/cutting by the cutting tools while holding an object (i.e. branch) with one of the cutting edges.
  • the cutting tools may be bulky or ergonomically less suitable which makes their application inconvenient for the common user.
  • the '974 reference provides a cutting tool.
  • the cutting tool includes a first and a second cutting element which can be moved relative to one another.
  • the cutting tool further includes a first and a second gripping element which can be moved relative to one another.
  • the cutting tool includes a drive unit which in at least one operating state is provided to at least support a movement of the second cutting element relative to the first cutting element via a drive force transmission element.
  • the drive force transmission element has a gear unit having a self-switching coupling unit.
  • the drive unit, the gear unit, the coupling unit and the drive element of the drive force transmission element are arranged in this order, on or in the first handle member.
  • the battery supplying power to the motor is located in the second handle member and is transmitted via a wire.
  • a cutting tool includes a top blade and a bottom blade.
  • the bottom blade is pivotally coupled to the top blade. Further, the top blade and the bottom blade together perform a cutting action on an object placed between them.
  • the cutting tool further includes a first handle and a second handle.
  • the first handle is operatively coupled with the top blade.
  • the first handle defines a front portion and a back portion.
  • the second handle is operatively coupled with the bottom blade.
  • the cutting tool is characterized in that, in closed position of the cutting tool, at least a part of the second handle at least partially encloses the back portion of the first handle.
  • the present disclosure provides a simple, compact and user-friendly cutting tool which allows ease of handling for common users, by moving some of the parts of its electric drive unit into a section of the handle that is normally not touched by the user when operating the cutting tool.
  • the partly enclosure of the back of the first handle by a part of the second handle in closed position also protects the cutting tool from obstacles unintentionally moving into the space between the two handles. This in particular helps when maneuvering in bushes and trees.
  • the movement of some of the parts of its electric drive unit into a section of the handle that is normally not touched by the user allows the placement of the users hand nearby the pivot point of blades and handles. By this even users with small hands can easily operate the cutting tool.
  • a battery of a drive unit is housed within the second handle. This helps in reducing the dimensions of the first handle so that the first handle remains even more partially enclosed within the second handle.
  • the drive unit includes a motor, a gearbox, a drum, a printed circuit board assembly (PCBA) and a battery to selectively provide the supplemental motor force.
  • This supplemental motor force by the drive unit provides the mechanical advantage to assist cutting action by the blades.
  • the drive unit may be enclosed within the second handle. Thus, the size of the first handle can be further reduced.
  • the drive unit is operatively coupled to at least one of the top blade and the bottom blade. Further, the drive unit is configured to selectively provide a supplemental motor force to assist a movement of at least one of the top blade and the bottom blade to perform the cutting action.
